831,121. Tools for trueing grinding wheels. LADINSKY, W. April 11, 1956 [April 21, 1955], No. 11037/56. Classes 60 and 124. A tool for trueing grinding wheels is in the form of a thin flat layer 1, Fig. 2, of a diamondcontaining metal matrix fixed between outer rigid members 3 of solid material, preferably steel, for presentation edgewise to the grinding wheel, the thin flat layer containing only one or two layers of diamond grains. The layer 1 may be sintered between the facings 3 or secured thereto by soldering or brazing. The tool may be of somewhat rectangular form as shown in Figs. 1 and 2 and secured by soldering or brazing or by bolts or set screws 7 in a holder 5 at the end of a stem 8 which can be fixed in the desired position when trueing a grinding wheel 9. As shown in Fig. 2, the layer 1 need not extend for the full length of the tool but only so far as to cover the extent to which it would be worn away in use. The tool may, alternatively, be of the disc or modified disc form shown in Fig. 4 and secured between clamp plates 106 by bolts 107, 107<SP>1</SP>, of which the bolts 107<SP>1</SP> may be of polygonal cross-section and pass through a correspondingly shaped hole in the tool. The tool may be indexed to present new working parts to the grinding wheel. In the modification shown in Fig. 7, the diamond-containing layer 201 is located in a slot at the end of a rod which is of square, circular or other cross-section, the limbs of the rod on the sides of the slot providing the desired rigidity.
